Access Cronicle Master GUI behind reverse proxy

[SprickW]

To access our web servers we use a nginx reverse proxy.

But when routing to our internal address:port and trying to access the cronicle GUI by it external address ... it shows "loading" forever.

Any hint?

we also use a nginx proxy with the following config:

upstream cronicle {
        server hostname01:3013;
        server hostname02:3013;
        server hostname03:3013;
}

server {
        server_name servername;

        listen 80;
        listen 443 ssl;
        ssl_certificate /etc/ssl/certs/ssl.cer;
        ssl_certificate_key /etc/ssl/private/ssl.key;

        location / {
                proxy_pass https://cronicle;
                proxy_no_cache 1;
                proxy_cache_bypass 1;
                access_log /var/log/nginx/cronicle_access.log;
                error_log /var/log/nginx/cronicle_error.log;
                add_header Pragma "no-cache";
                add_header Cache-Control "no-store, no-cache, must-revalidate, post-check=0, pre-check=0";
        }
}

I think I do not need an "upstream" definition as I just have one cronicle server, right?

As certbot created my certificates I left the definitions for "listen" and "ssl_certificates" as they were generated by certbot.

So finally I just added the 2 lines for the log and the two line for the header.

But the effect is just that the loading pop-up doesn't show up, only the cronicle frame is show with an empty main window.

Servus @SprickW,
I was also on the same page as you.
I went through hell to find this info months ago. Alas, here is the configuration that lead to my successful run.

server {
    server_name yourservername.com;
    ....
